The MacDonald Rhubarb is an excellent variety for commercial and home growers. It can grow up to 4' wide with vigorous upright growing habits. It produces large tender red stalks with huge heart-shaped leaves, ready for harvest in May. This self-pollinated plant is both cold-hardy and heat-tolerant and will last for years and can be divided every year in the spring if needed. This variety shows resistance to root-rot problems. Grows best in zones 4-8.
